The Yonex Polytour Rev 1.25 string is an eight-sided monofilament, equipped with SIF (Silicone Oil Infused Filament) technology, a process which, thanks to the silicone oil infused into the string, increases its performance, reducing friction between the strings to increase snapback and bring more spin to the ball.
The Polytour Rev offers 4.6% more spin, 6.2% more speed and 13.4% more clear play than a leading competitive model. It also boasts better tension retention to give players longer life.
